Insights
Early sensory processing in toddlers is linked to social responsiveness later in childhood. Assessing sensory patterns may aid in the early detection of autism spectrum disorder (ASD).
Area of Science:
- Developmental psychology
- Pediatric neurology
- Autism spectrum disorder research
Background:
- Investigating the link between early sensory processing and later social development in children.
- Exploring the potential of sensory processing assessments for early autism spectrum disorder (ASD) detection.
Purpose of the Study:
- To determine if sensory processing characteristics at 18 months predict social responsiveness at 3 years.
- To assess the utility of sensory assessments in identifying children at risk for ASD.
Main Methods:
- 180 children (91 boys, 89 girls) participated.
- Mothers completed the Infant/Toddler Sensory Profile (ITSP) at 18 months and the Social Responsiveness Scale Second Edition (SRS-2) at 3 years.
- ITSP measures sensory patterns; SRS-2 assesses ASD-related social communication, interaction, and behavioral traits.
Main Results:
- Significant correlations were found between ITSP scores at 18 months and SRS-2 scores at 3 years.
- Early sensory processing characteristics are associated with later social difficulties characteristic of ASD.
- Findings suggest a connection between sensory processing and the development of social behaviors relevant to ASD.
Conclusions:
- Assessing sensory processing in young children can enhance early identification of ASD risk.
- Integrating sensory evaluations into screening protocols may improve ASD detection accuracy.
- Early identification facilitates timely intervention and support for children with ASD and their families.
Background:
This study investigated the relationship between sensory processing characteristics at 18 months and social responsiveness at 3 years of age in children, to explore the potential utility of sensory processing assessments in the early detection of autism spectrum disorder (ASD).
Methods:
Participants included 180 children (91 boys, 89 girls) born at an obstetrics and gynecology clinic. Mothers completed the Infant/Toddler Sensory Profile (ITSP) when children were 18 months old and the Social Responsiveness Scale Second Edition (SRS-2) at 3 years. The ITSP assesses sensory processing patterns based on neurological threshold and behavioral response/self-regulation, while the SRS-2 measures ASD severity, including Social Communication, Interpersonal Interactions, and Restricted Interests/Repetitive Behaviors.
Results:
The results revealed significant correlations between the ITSP quadrant and section scores at 18 months and SRS-2 scores at 3 years, suggesting that sensory processing characteristics in early childhood may be associated with subsequent social difficulties associated with ASD.
Conclusion:
These findings highlight the potential value of assessing sensory processing in young children to improve early identification of ASD risk. Incorporating sensory processing evaluation into screening protocols may provide a new perspective and enhance the accuracy of early detection efforts, enabling earlier intervention and support for children with ASD and their families.
